Executive summary:

The skin irritation potential of the test material was investigated in accordance with the standard methods prescribed by the Consumer Product Safety Commission of the USA in The Code of Federal Regulations, Title 16, Section 1500, 41.

The test material in distilled water was applied to the intact and abraded skin of Albino rabbits and the skin irritation assessed using a patch test technique that was carried out in an occlusive fashion. Animals were observed for 72 hours.

Evaluation of skin reactions (scores) was not provided. The summary report states that no animals showed any observable response to treatment throughout the 72 hour observation period.

Under the conditions of this study, the test material is non-irritating to skin.
